This close-coupled end suction pump integrates a cast iron casing with a bronze impeller and a bronze shaft sleeve. The dry shaft design prevents contact between the circulating fluid and the shaft, mitigating the need for corrosion-resistant shaft materials. A mechanical seal utilizing a ceramic seat half and EPT rubber seals the assembly, which operates at a maximum pressure of 125 PSI without a wear ring. This configuration facilitates seal maintenance through a slip-on shaft sleeve. Suction and discharge connections incorporate standard pressure tappings, and the design allows for the installation of an optional filter via flush seal line taps to protect internal components from non-condensable particles.
The 25 HP premium efficiency ODP motor operates at 1750 RPM and incorporates Aegis grounding, powered by a 200-230V 3PH supply with a DOE PEI rating of 0.48. The 'S' in the SCI series denotes Taco's advanced Self-Sensing technology, which eliminates remote sensors and field wiring by using internal mathematical algorithms to calculate system resistance and automate variable flow. The included VFD is configured with a fused disconnect without bypass and holds an enclosure NEMA 1 / IP 21 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
